Title: Combustion apparatus for liquid fuel
IPC: F23D11/46
Filed: 1972-08-10
Abstract: 1379799 Liquid fuel burners MITSUBISHI DENKI KK 10 Aug 1972 [10 Aug 1971 13 Oct 1971 20 Oct 1971 31 March 1972] 37419/72 Heading F4T Liquid-fuel combustion apparatus comprises a liquid fuel reservoir 601, Fig. 6, a fuel pump 602, a fuel vaporizer 605, a combustion chamber 608, a fuel vapour condenser 609, and switching means for selectively switching the flow of vaporized fuel to the condenser during awarmup period and for thereafter passing vaporized fuel to the combustion chamber. The switching means may comprise a valve 611, which is open during the warm-up period, and an ejector structure 606 having a nozzle at the outlet of vaporizer 605, an outlet 607 to the chamber 608 and a pipe leading to condenser 609. When valve 611 is open, all the fuel vapour passes into pipe 610 and none to outlet 607. A second switching means comprises a spring-biased ball-valve which opens above a predetermined pressure so that the fuel vapour flows to the condenser or the combustion chamber when a valve between the vaporizer and combustion chamber is closed or open respectively, Fig. 2 (not shown). An alternative embodiment of the apparatus, Fig. 8, comprises a fuel pump 810 and constant-pressure means 811 supplying fuel to a vaporizer 826, heated during warm-up by an electric heater 816 and thereafter by the heat of combustion, supplying a nozzle 822 or a condenser 821 via valve 818 having a solenoid actuator 819 selectively to close an outlet of valve 818 to the condenser 821 or an outlet to the nozzle 822. The valve outlet to the condenser is via a passage receiving a valve-operating stem whereby said passage provides a flowrestriction to reduce the vapour pressure acting on a seal at the point at which said stem passes out of the valve-body to connect to the solenoid 819 external thereto, Fig. 11 (not shown). Vapour is condensed in the condenser 821 to pre-heat combustion air supplied by a blower 801 to a preheating chamber 802. The heat-transfer path between the heater 826 and an inner wall of the chamber 802 is arranged so that the vaporizer is normally at about 250‹ C., for kerosine, and chamber 802 is at 100‹ to 150‹C. Alternatively, a second electric heater may heat the chamber 802 during warm-up. A capillary tube 827 between the vaporizer and a fuel supply line 817 thereto is stated to act to maintain the heat output of the apparatus substantially constant. Fuel vapour from nozzle 822 and preheated air from the chamber 802 pass to a mixing chamber 823 during combustion and thence via openings 825 to a mixture-collecting chamber 803 leading via an apertured disc 806 to the combustion chamber 804 which has an ignition plug 808.

Abstract: 1,211,012. Packaging-machines; endless conveyer; cigarette hopper. E. SERAGNOLI, A. SERAGNOLI and M. C. SERAGNOLI, [trading as G. D. SOC. IN ACCOMANDITA SEMPLICE DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 15 Feb., 1968 [20 April, 1967], No. 37537/67. Headings B8A, B8C and B8S. Pushers 4a, 4b, 4c are reciprocated to enter the base of a hopper 1 and impel one layer of cigarettes each from the hopper into receptacles 9 on an intermittently movable chain conveyer 10 towards either side of which sensing members 59, 59a, Fig. 4, are oscillated through rack and pinion mechanism 61, 60 under control of a cam 54 in order to sense the absence of cigarettes in the batch, the sensing members closing an electrical circuit to operate an expeller 64, and the complete batches being carried to a position where they are transferred by a pusher 106 into the control of jaws 77 of a rotatable conveyer wheel 78. The hopper 1 has a wall portion 11 which is oscillated about a shaft 12 under control of cam and roller mechanism 36, 37 and tappet shafts 39, 40. A control member 47 allows the wall portion 11 to be detached from the tappet shaft 40 by turning plates 43 which engage in a groove 40b at the end of the shaft. The lower part of the hopper wall is openable, but is normally held shut by a spring loaded rod 49. The base of the hopper is stepped to enable the formation of three layers of cigarettes in each batch by the pushers 4a-4c. The upper surface of the pushers is grooved to retain the cigarettes overlying the layers removed. A control shaft 13, from which the movement of the pushers 4a-4c is derived, turns through a pinion 50 the cam 54 which controls the sensing members 59, 59a; it also governs the movement of a cam 55 and roller 68 the purpose of which is to return the expeller 64 to its initial position. A third cam 56, which is in driving connection with cams 54 and 55, is engaged by a roller 69 to control the movement of a guide wall (not shown) and thereby to assist in the transfer of cigarettes by the pusher 106 into the jaws 77 which are opened to receive the batch. A shaft 82 driven from the shaft 13 through pinions 80, 81 drives the chain conveyer 10 through intermediate mechanism which includes a Geneva wheel 97 and rollers 96. The shaft 82 also carries a cam wheel 98 engaged by a roller 100 through which a support sleeve 104 for a rod 92 of the pusher 106 is given an arcuate return path in order to enable the pusher to avoid successive containers 9 on the chain conveyer 10 after delivery of a batch of cigarettes to the grippers 77.

Title: Looms
IPC: D03C13/00
Filed: 1977-09-12
Abstract: Series shed-weaving machine, in which a plurality of sheds travel in the warp direction during operation. The sheds are maintained by shed-holding elements, so that a plurality of wefts can be inserted at the same time. The shed-holding elements consist of pivoting wings (12) which are introduced into the warp threads (9) in a position parallel to the warp direction (6). They are pivoted through 90 DEG in the shed, so that they are in the weft direction. In this position, all the pivoting wings form a continuous shed-holding element extending in the weft direction. The entire pivoting wings can be moved further in the warp direction in this position. This makes it easier to introduce the pivoting wings into the warp threads and to maintain the travelling shed during operation, and an operationally reliable continuous shed-holding rail can be formed from the pivoted pivoting wings. <IMAGE>

Title: Improvements in and relating to the production of styrene compounds
Inventor: HANDLEY MELVIN FULLER
IPC: C07C29/66
Filed: 1956-12-14
Abstract: A process for the preparation of an arylethylene chlorohydrin comprises reacting a nuclearly alkylated monovinyl aromatic hydrocarbon having from 8 to 10 carbon atoms at a temperature between 0 DEG  and 60 DEG  C. with an aqueous solution of an alkali metal-or an alkaline earth metal hypochlorite in proportion of from 1 to 2 chemical equivalents of the hypochlorite per mol. of the vinyl aromatic hydrocarbon while acidifying the reaction mixture and maintaining the same in a pH range between 4 and 6 to produce a reaction product containing an aryl-ethylene chlorohydrin.  A process for the preparation of an aryl ethylene oxide comprises separating from the reaction product obtained above the water immiscible organic layer containing the aryl ethylene chlorohydrin and fractionating to separate the chlorohydrin, reacting the latter with an aqueous solution of an alkali metal hydroxide at a temperature below 80 DEG C., e.g. between 20 DEG  and 60 DEG  C., separating the organic layer containing the arylethylene oxide from the reaction product and fractionating the same to recover the arylethylene oxide therefrom. In a modification of the above process styrene is employed as starting material and styrene oxide is obtained as product. Additional products specified are methyl, dimethyl and ethyl styrene oxides. Hypochlorites specified are sodium and calcium hypochlorites. Acidification may be carried out with an acid, acid anhydride or a solution of an acid salt, e.g. carbonic and hydrochloric acids, carbon dioxide or sodium bicarbonate.  The hypochlorination products may be mixed with a perchlorinated aliphatic hydrocarbon solvent, e.g. carbon tetrachloride or perchlorethylene to facilitate separation of the organic material.  p-Methylstyrene oxide is stabilized by addition of 1-nitroso-2-naphthol before distillation. The processes may be carried out continuously. Examples relating to the production of styrene- and p-methylstyrenes and chlorohydrins are furnished.  Apparatus for carrying out the process is described with reference to a Figure (not shown).

Abstract: 1,170,174. Composite tobacco-smoke filters. D. W. MOLINS. 21 Aug., 1968 [22 Aug., 1967], No. 38582/67. Heading A2C. A method of making a composite tobacco-smoke filtering rod having a particulate filtering material enclosed in a space defined between two smoke-permeable cylindrical elements within a tubular wrapping includes the step of causing the two elements to be relatively displaced to reduce the volume of said space and there by increase the degree to which the material packs the space. Preferably the wrapper is coated with a heat sensitive adhesive to allow heat sealing of the elements to the wrapper after displacement of the elements therein. Where the two elements are filter stubs, one may be moved towards the other inwardly of one end of the wrapping to define a recessed end face, which recess may subsequently be removed by cutting through said one element which should originally be oversize to allow for this. The two elements may alternatively be a filter stub and a wrapped tobacco rod whereby a filter cigarette is directly produced. Where double length composite filter stubs are to be formed, the outermost element at each end is displaced inwardly.

Title: Circuit for selecting both upper and lower sidebands
IPC: H04J1/04
Filed: 1956-12-19
Abstract: 817,696. Radio transmitting systems. COL. LINS RADIO CO. Dec. 19, 1956 [April 12, 1956], No. 38719/56. Class 40 (5). In a single sideband transmission system in which the signals are modulated on to a subcarrier and one sideband is selected, this sideband is selectively transmitted as either the upper or the lower sideband of a carrier having a frequency n + 1 times the sub-carrier by mixing the single sideband signal with a second subcarrier which is switched so as to have either a frequency n times the first sub-carrier or n + 2 times the first sub-carrier and then selecting the desired band by a filter centred on a frequency n + 1 times the first sub-carrier. The audio signal e.g. 1 kc/s., is combined in a balanced modulator 6 with a 250 kc/s. sub-carrier generated at 7. A mechanical filter 8 selects the resulting upper sideband (251 kc/s.) and this is applied to a second mixer 14. Also applied to the second mixer 14 is the 250 kc/s. sub-carrier which has been multiplied either by 2 or by 4. The multiplication factor is selected by a switch 10. If the sub-carrier is multiplied by 2 the output of the mixer 14 includes a 751 kc/s. (upper sideband) signal, and if the sub-carrier is multiplied by 4 the output of the mixer 14 includes a 749 kc/s. (lower sideband) signal. These signals are selected by a band-pass filter 11 centred on 750 kc/s. The output of filter 11 is modulated on to a main carrier at 15.

Title: Centrifugal casting devices
IPC: B22D13/10
Filed: 1971-08-18
Abstract: 1343939 Centrifugal casting machines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 18 Aug 1971 [8 Sept 1970] 38828/71 Heading B3F A centrifugal casting machine has two halfmoulds 1 and 2 kept in their assembled position during the casting operation with the assistance of inertia weights 26 and levers 25 acting on said half-moulds and is characterized in that each weight 26 is attached to the major arm of a crank lever 25, the minor arm of said lever 25 carrying rollers 28 which bear against the halfmoulds. The crank levers 25 pivot about shafts 24 and the rollers 28 each bear against a flat outer surface of the mould. The mould is located within a cylindrical frame 13 made up of four angle-sections 14 held in position by steel rings 15, and the whole assembly rotatably driven by a motor 19 via a friction coupling 21. When the assembly is rotating the centrifugal force causes the weights 26 to tend to move away from the axis of rotation; this causes the levers 25 to pivot about the shafts 24 and the rollers 28 to move towards the axis of rotation, thus pressing the half-moulds against each other. The arrangement is such that the assembled half-moulds are automatically centered with respect to the axis of rotation. The mould is provided near one end thereof with a circular internal groove (7) into which a washer (8) may be inserted. That part of the mould, beyond the washer acts as an overflow chamber whilst the bore of the washer determines the internal diameter of the tube being cast. The said tube may be subsequently cut up to form cylinder liners.
